Stocks in Hong Kong and Shanghai climbed Monday and helped lift other Asian bourses after Beijing’s surprise interest-rate cut bolstered optimism over the outlook for the world’s second-biggest economy.

Hong Kong’s benchmark index jumped 2%, the biggest advance in more than two months, while a measure of Chinese-listed firms in the city — the Hang Seng China Enterprises — rallied 3.8% and into positive territory for the year. Shanghai rose 1.9%.
